Installation Steps
- Prepare Doors: Attach the butt hinges to your door panels. For 4-door styles, ensure the anti-collision strip is applied diagonally on the door as instructed.
- Install Rollers: Secure the fixed and adjustable rollers to the top of your door panels using the provided hardware.
- Install Bottom Pivot Plate: Determine the fixed pivot position on the floor. Drill a hole and insert the brass sleeve, then secure the bottom pivot plate.
